Fume extractor is used in laboratories to extract harmful chemical fumes. When I was working in an electronics lab, I had a lot of soldering to do and we had these fume extractors that cost upwards of $200. All these fume extractors were a fan and filter that sucked the soldering fumes. It surely was overpriced and I thought to myself that in developing countries, these expensive equipments won't be used leading to harmful working environments. A low cost solution would change this. So, I designed this shell that holds a filter and fan. The choice of filter is left to the user. The user can select carbon activated filters(like I did) or HEPA filters or formaldehyde filters, etc. The manufacturers that made these equipment made their filters in odd shapes. So, this meant that the consumer had to buy the filters from the manufacturer at a high price. This is clearly unfair. With a 3d printed shell, we can design the filter holder for filters that are readily available in the market. This comes at a great advantage. So, lets get into the stuff required for the fume extractor
